How CHECK LOB identifies violations

You can find and resolve violations by reviewing messages that the CHECK LOB utility issues.

CHECK LOB issues message DSNU743I whenever it finds a LOB value that is invalid. The violation is identified by the row ID and version number of the LOB. You can resolve LOB violations by using the UPDATE or DELETE SQL statements to update the LOB column or delete the row that is associated with the LOB. (Use the row ID from message DSNU743I.)
